RAIL-BOND. f

`Specication,of Letters Patent.

'Patented Aeg. 4., 190s.-

Application filed November 25, 1904, Serial No. 23Q,164. Renewed October9, 1907. Serial No.'1l3`9,6,658.'

` citizen of' the United States, resident of Cleveland, countyoi-Cuyahoga, and State of Ohio, have invented ,anew and useful Imrovementin Rail-Bonds, of which lthe folowing?r is a speciiic'ation, theprinciple ofthe invention being herein explained and the best mode 'inwhich I have contemplated applying that principle, so as to distinguishit trom other inventions.

My in ven tion relates to devices for bondingv abutting rails ofelectric railways, `its object being to providea bond which ymay heeiliciently attached tosaidrails land which is economical initsconstruction.`

4ticularly ada ted for use in connection with the electrica process of`bondingirails by brazing or soldering, described and claimed;

in an application,` for U. S. Letters Patent filed even date herewith.The saidinvention` in bonds is hereinafter,fullydescrihed andparticularly set forth in the claims.

The annexed drawing and. thei following description set forth iny detailcertain means einbotying the invention, lsuchdiselosed 4 4, Fig. 3.Figoillustrates theutilizameans constituting but one otyario'us me.Achanieal forms in which therprlnciple of the,A

invention maybe used. l

y In said annexedy lraWinUz-fIigurel represents a frontelevation` ofi:Aabond `embodying my invention, the ends of thetwo rabutting rails t0which yit is` `attached,..being shown -in dotted lines. 1v Fig.LZrepresents a section of said hond `takenupon -thepl.ane

indicated byline 2%2, Fig. 1.. Figrepre-v sents a front elevation'ofvthe sheetzofbrazing or soldering material ``forming ypart .oiltheeompletebond. l Eig. 4 re resents a'section of said bra-zing material taentupon the line tion of the formgof1 suclifbrazing material to retain aflux-'Where such` flux/.is used-.fte increase the usibility of theparts.

The bond embodying myinventionconsists of a main conducting ,element A,Vformed of laminations of copper, as shown and hav-` in'g two terminal.parts a, (1.@ These terminal.`

parte extend laterally as shown in dott-ed ines in Fig.` 1, so as-topresent there uired amount of contact surface..` Uponeac 1 ter` `minalApart is secured a solder or braze -portion A Each of these portionsconsists of a rectangular sheet of sultablefmetalsuch asV brass,provided With an up er iiange a', vas shown vin Figs,A 3 and 4..' T iemainv portion ot the sheet is rovided with apseries of 0 vpositelydirecte indentations e2., alternate y` larranged 'as shown, so 'asytodform aseries of protuberances projecting from opposite sides of thevbrazeportions. This ybra'zc' ,portion is placed n on the terminalIper-teo `'as to` ing the'indented character ofthefbrazingis. The bondembodying my inventionis par-f` `imparted thereto for the purposeof.reducing jthe `conducting Contact surface and thereby ,increasing theelectrical Iresistance of the parts when used. in connection `with thesaid method. These indentations also rovide a convenient medium forholding a ux Where `such iux is used to increase the fusibility of theparts when subjected to the electrically generated heat. lin such case,theindentations readily receive and retain such yiux, `designated byletter a3, Fig. 5, and." elciently prevent the detachment thereof fromtl'ie'braze portion. HThis flux is usually ap- .plied in ahquidorfseini-liqiiid condition and `then permitted to dry out whereby it isleft 4 in a solidv condition in theyindentatioi1.'v

Inasmuch as the particular constitution of the sheets A will dependu yonvarious considerationanot `merely-iin t e matter of results'obtained butof expediency and c0nvenience use,` itwill be understood that I hereinuse the terms solder and braze indifferently, -y meaning thereby anysuitablev material or composition thatwill serve to unite the metal `ofthe. bond with that of the rail. As a general term applyin to eithersolder or braze, I shallaccording y use the phrase cementing material.

Other ,modes of applyingA the dprinciple,of`

my invention may. eem loye instead .of the one explained, change o eingmade as re garde the means herein disclosed, rovided thel means .statedby any one of thefollowing claims or the equivalent of such stated meansbe employed. 1 l

[Iftherefore particularly point out and`dis tinctlyvclaim as myi'nventionrl". A railfbond oomprisin a main conducting, element havinglateralIy extending tere havingsits lower edge bent under the laterallyextending portion of such part whereby such sheet \is held in place uponsaid terminal afi?. s ,f P 2. A"`-1rail-bond comprising a conductinrelement, and sheets ot' ceinenting materia attached to the respectiveterminal portions of said element, said sheets having their outer facesformed with projecting protuberances, whereby the contacting area ofsuch faces is decreased.

3. A rail-bond comprising a conducting` element, and sheets o' cementingmaterial attached to the respective terminal portions of said element,said sheets being of nndulate Icross-section, whereby outwardlyprojecting protuberances are formed.

4'. A rail-bond comprising a conducting element, and sheets et'cementing material attached to thev respective terminal portions of saidelement, said sheets being provided with oppositely directed.YIigidentations alternately arranged to form proltnbcraiices projectingfrom their opposite sides'. i

5.v A railfbond comprising a main conducting element having laterallyextending terminal parts, and sheets ot cementing material having theirouter and inner surfaces of undulate cross-section, whereby outwardlyprojecting protuberances are formed.

6. A rail-bond comprising a main conducting element having laterallyextending terminal parts, and sheets of cementing material for each suchpart, each such sheet liaving an outer contact face of less area thanits outer face and an inner face only in partial Contact ywith thecorresponding terminal part, cach suchf sheet being formed with an upperflangre-portion resting upon the end surface' ofthe .correspondingterminal part an ing itslr'iwer edge bent under the late `llyl'extending portion of suoli part wh r Iy's'neh sheet is held in placeupon said tei ninal part. 'y

,71"Al`rail-b/ond comprising a main conduct element having laterallyextending terminalparts, and sheets of cementiiig material formed withinwardly and outwardly rejecting protuberances, cach such sheet keingformed with an upper flange-portion resting upon the' end surface of therespective terminal part and haviiigits lower edge bent under thelaterally extending portion of such part whereby suoli sheet is held inplace upon said terminal part.

8. As a new article of manufacture, a railboiid comprising a mainconducting element, sheets of cementing material attached to therespective terminal portions thereof, .said sheets having their outerfaces formed with projecting yrotnberances, 'and a flux depositedin theindentations intermediate hctween such protnberances.
